Iâ€™m not too convinced about the cooling fins, they look insufficient. Reminds me a bit of the Energy + which turned out to be a real bummer in the heat and noise department. Regardless, a review here at SPCR would be interesting.

The cooling fins are actually more than sufficient for the combination of low power output and high efficiency. Since it's 80%+ efficient, and at max it can output 450W, the maximum amount of heat generated would be about 90W in a worst-case scenario. With that combo of heatsinks and the fan, it's more than enough.

Seasonics have always had pretty small cooling fins, even the old S12 models. I don't think that's ever going to be an issue with a moderate power psu as long as the other aspects of the psu are good. I'm glad I have another lower cost alternative to the HX series to recommend.

Iâ€™m aware of the theoretical approach, as Iâ€™m aware of what it states, mean and suggest. However, Iâ€™m equally aware of its work place which tends to be something else then a work bench cooling itself . An experience that the Energy + quickly found to be less pleasant than the cosy place in the padded shipment box.

The fins in the Energy + was even smaller than those in the S12 range. I suppose thatâ€™s one of the reasons as to why it performed so poorly, running hot and fan ramping up, even during moderate loads.

It seem the VX450W coped just fine in both reviews when they pumped a fair bit of heat through it so I don't see this being a concern for SPCR adherents as they are unlikely to biuld such poorly ventilated systems.

I can't wait for this to be released downunder (but then the power craze means the ST-40EF isn't available here so we may miss out on the VX450 as well )

Since it's practically identical to S12 II, one would expect it to cope with heat w/o any problems. High efficiency kicks butt. Hi quality caps kick butt. You don't need masses of air to cool this PSU. FSP GLN/Be QUiet Straight Power has razorblades instead of heatsinks and works just fine.

The VS450W has an amient noise level of 28dba, but the S12 has 17 dba. I'm looking for a quiet PSU, I think the S12 still is the best option. The HX520 has modular cabling and 2 dba more noise (should not be notisable). But after reading all wining noise post of the HX520, mayne the S12 will be more safe.

Guess it could be viewed as an unhealthy family environment, eeh... I meant to say business philosophy, my bad.

Yeah, I have never had any "errors" with cables detaching and such in the other end (that is the end attaching to mobos, drives and so on), so I wouldn't think it was a problem in the PSU-end either.

I would guess that modular cables could be more prone to error (viewed to in which way they are connected) in causing signal disturbance (noise for instance), worse if they were to be of lesser quality, more error prone.

Tip

If a cable detach, fetch some duct tape and tape that sucker into submission

Corsair's HX series PSUs sold because they were effectively modular Seasonics. The VX seems virtually identical to any similarly rated Seasonic.

The main advantage to me is that corsair is a well known brand and easily to get in a lot of places. Also unlike seasonics, you might actually find some rebates/discounts...I got my HX520 for $80 and I totally love it. I'll definitely recommend the VX450 to people if it's somewhere under $70, assuming there isn't a better seasonic available.

I just want to stress that during that test, it was the background noise level that was 28dba, so in effect it would be hard to measure any noise-level below that. Thus we have to wait for a review done in a more quiet environment to actually being able to tell how quiet the VX is. I for one hope that it'll be very quiet, cause it seems like a good addition to my next comp!
